2 . Not that long ago, the world wondered whether clean energy could survive without government support. Now the question is how far it can spread. The number of electric vehicles, which was about 1 million in 2015, last year reached 2 million. In electricity generation, too, trend is with the greens. In the first half of this year, wind, solar and hydro generated a record 35% of Germany's power.
Greater success is breeding greater ambition. California is proposing to reach 60% renewable energy by 2030. 176 countries have clean-energy goals. Hawaii, America’s most oil-dependent state, has promised to be 100% renewable by the middle of the century and so have 48 poor countries vulnerable to climate change. This week the number of multinationals making a commitment to running their operations on 100% renewable energy rose to 100.
But not every target is helpful. To see why, consider that goal of 100% renewable energy. It makes solving climate change seem easy. In fact, though wind and solar can generate the whole country’s electricity some day, renewables still account for less than 8% of the world’s total power output. Moreover, cleaning up electricity is only part of the battle. Even though gas-fired heating and cooking can be at least as big a source of greenhouse-gas emissions, renewable heating gets little attention. Transport policy is unpredictable, too. Car manufacturers may hit their goal of annual sales of 10 million electric vehicles in a decade, but battery-powered road transport, shipping and aviation (航室) are dreams. A much-quoted claim that America could rely on wind, solar and hydro alone for its electricity has recently been bitterly criticized by a group of respected academics.
Most importantly, a 100% renewables target confuses means with ends. The priority for the planet is to stop net emissions (净排放量) of greenhouse gases, especially carbon dioxide. Putting too much emphasis on wind, solar and other renewables may block off better carbon-reduction paths. New technologies, such as “direct air capture” systems designed to separate carbon dioxide from the air, may in time prove vital. Likewise, greater energy efficiency could reduce emissions by even more than using renewables would.

3 . How To Eat Better for the Planet
You're environmentally conscious - and hungry. Here are answers to all your coo-friendly food questions.
Does what I eat have an effect on climate change?
Yes. The world's food system is responsible for about one quarter of the planet-warming greenhouse gases that humans generate each year. That includes raising and harvesting all the plants, animals, and animal products we eat.
How exactly does food contribute to global warming?
When some forests are cleared to make room for farms, cattle, sheep or other livestock, some serious problems may come up.
What about chicken?
A number of studies have found that chickens, ducks, and other birds have a lesser climate impact than cattle or sheep kept on a farm.
Is organic produce better for the climate?
Organic produce is grown without synthetic fertilizers or pesticides, but that doesn't mean it's necessarily better than conventionally grown produce from a climate perspective.
It's true that one person alone just makes a little bit in the climate problem. On the other hand, if many people made changes to their diets, that could start to add up. Experts have argued that it would make a big difference if the world's heaviest meat eaters scaled back - even moderately.
A.Does what we eat matter? |
B.Can I really make a difference? |
C.Organic farms often require more land. |
D.Modern-day chickens are bred to be extremely efficient. |
E.Processing, packaging, and shipping food are also part of it. |
F.Advances in chickens breeding are helping to reduce the cost of it. |
G.Large stores of carbon released into the atmosphere heat up the planet. |

5 . It's not always easy to run an energy efficient house. But there are some simple things anyone can do.
Go LED with your lighting.
There are sevenal benefis to switching to energy efficient light bulbs. One of them is saving money- though the LED bulbs might cost more than traditional bulbs, the average saving on LED bulbs is $ 75a year._
Don't run your air conditioner constantly
As the weather starts to warm, you might be thinking about the right time to turrn on your air conditioner. _
On those days when you treat a large crowd and are low on time,don't beat yourself up if you have to use disposable(一次性的) dishware. This method reduces your water usage and saves energy. And as a bonus, if your city offers roadside recycling, your paper plates may qualify.
Update your insulation(隔热)
All that work you're doing to save energy in your home could go to waste if it's not properly insulated. If you can't insulate the whole house, pay special attention to the roof: it reduces air flow from outide. By updating your insulation,you're saving money.
Take showers instead of baths
A full bathtub requires about 70 gallons of waler.
A.But do you really have to? |
B.You should use your air conditioner smartly. |
C.Tum off water when not using it. |
D.Plus, you needn't change them frequenly. |
E.Don't feel guilty about using paper plates. |
F.And it's also easier to control your home temperature. |
G.Even if you don't fill it to the top, it still uses much more water. |
6 . Let's take a minute to think about the water we use. The human body is 60% water and we need to drink lots of water to be healthy. When we are thirsty we just go to the kitchen and fill a glass with clean water.
The truth is that we are lucky enough to have clean water whenever we want,but this is not the case for many people around the world.
A.We use water indirectly too. |
B.Every system in our body depends on water to function. |
C.It is to inspire people to learn more about water-related problems |
D.If children walk many hours a day to get water,they can't go to school. |
E.Did you know that around 750 million people do not have clean water to drink? |
F.In 1993 the United Nations decided that March 22nd is the World Day for Water. |
G.In this way,they know how it feels to walk a long distance carrying heavy bottles. |
7 . What is ecofashion? Eco-fashion is about making clothes that take into account the environment, the health of consumers and the working conditions of people in the fashion industry.
There is some concern that eco-friendly fashions are just a trend that we will eventually grow tired of but in fact, more and more people are concerning about this and we can make sure that doesn’t happen.
A.Then, how to solve the problems? |
B.They relate directly to our personal health. |
C.Because choosing ecofashion can also contribute to our personal health, though it is mostly done by way of keeping the health of the planet. |
D.In addition to this, there is a lot of waste produced in the process, especially in the form of polluted water. |
E.The fashion industry has developed quickly. |
F.On the other hand, as consumers we can all make contributions by selecting environmentally friendly clothing and reducing clothing consumption. |
G.A closer look at the fashion industry points out many problems. |
8 . The world itself is becoming much smaller by using modern traffic and modern communication means. Life today is much easier than it was hundreds of years ago, but it has brought new problems,
Man has been polluting the earth.
The earth is our home. We must take care of it.
A.The more people,the more pollution. |
B.One of the biggest is pollution. |
C.Air pollution is still the most serious. |
D.Many countries are making rules to fight pollution. |
E.That means keeping the land,water and air clean. |
F.I hope scientists can find ways to solve the serious problem. |
G.Strange diseases have appeared in some places because of pollution. |
